CHECK FOR PlCKER-IVIOTIONS OF LOONIS.

SPECIFICATION forming part of Letters Patent No. 776,399, dated November29, 1904. Application filed .lpril 25 1904. Serial No. 204,768. (Nomodel.)

To all whom, it mcty concern:

Be it known that I, CHARLES O. HUNTOON, a citizen of the United Statesof America, and a residentof Somers, in the county of Tolland and Stateof Connecticut, have invented certain new and useful Improvements inChecks for Picker-Motions of Looms, of which the following is a full,clear,and exact description.

This invention relates to a check device or appliance forthe'picker-motion of a loom, so that the means for making the pick willbe without excessive violence, especially at the latter portion of itsmovement, whereby jolting is avoided and the strap connecting thepicker-stick and sweepstake is relieved from wear, and consequently thelatter will remain suitable for use for a greatly-increased time.

The invention consists, in part, in the combination with a rock-shafthaving a lever-arm, in connection through the usual sweepstake with thepicker-stick, havinga lever-like abutment or horn, of a yielding bufferarranged in the line of movement of said abutment or horn and arrangedto be contacted with by the latter at the final portion of its movement,said buffer having a spring appurtenant thereto and against Which ityields.

The invention furthermore consists in the combination of parts ofparticular construction and arrangement, substantially as hereinafterfully described, and pointed outin connection with the accompanyingdrawings.

In the drawings, Figure l is a vertical sectional View through a portionof the end frame of a loom and showing substantially in elevation thepresent improvements in conjunction with the picker-stick. Fig. 2 is anelevation as seen looking facewise at the end frame of the loom and atright angles to the view, Fig. 1. Fig. 3 is a perspective view of alever-like appliance hereinafter referred to.

In the drawings, A represents a portion of the end frame of the loom,inside of which the picker-stick B is mounted in the usual manner, thesame having its throw or pick imparted thereto, as most commonlyperformed, and D represents a rock-shaft, preferably square,horizontally ranging across the end of the loom, journaled for itsrocking movement in suitable bearings and having the lever-arm Eupwardly extending and connected through the sweepstake F and lugstrapwith the picker-stick. An oscillating or rocking motion is imparted tothe said rock-shaft in a positive and forcible manner. The rock-shaft Dis provided with a shoe or fitting comprising a huba, having a squaredaperture 7) therethrough and having a more or less horizontally andsomewhat curved abutment or horn (Z extended toward the end frame. Abovethe said horn (Z a bracketcasting G is bolted to the loom-frame, thesame having horizontallyextending lugs ff, which are understood ashaving alined vertical apertures g therein for the guidance of thevertical buffer rod or bar J, which may have a vertical play limited inthe downward direction by the abutment-collar It above the topbracket-lug f, and between the bracketlugs and sufficiently below theupper one is an abutment-collar 2', between which and the upperbracket-lug is the spiral spring 7', encircling the buifer-rod J and inmore or less compression for downward reaction. Both collars 72. and areadjustable, the upper one, it, being to vary the normal downwardposition of the buffer, While the collar e'by being adjusted varies thecompression of the spring, and consequently enables the buffer to berendered sensitive or yielding only under considerable resistance.

The picker-stick having been retracted to the position of the dottedlines in' Fig. l is swiftly drawn to its position shown in the fulllines, Fig. 1, through the rocking movement of the shaft D and theleftward swinging movement of the lever E, and as the pickerstickapproaches to the limit of its leftward position at the final portion ofthe picking action the horn (Z comes against the lower end of the bufferand checks or slows up the mo tion, preventing impact or violence,saving the picker connection from unnecessary strain thereon, andconducing to lessened noise of action.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is

1. In a loom, the combination with arockshaft having a lever-arm inconnection with IOO the picker-stick, having a lever-like abutment orhorn, of a yielding bufier arranged in the line of movement of saidhorn, and arranged to be contacted with by the latter at the finalportion of its movement, aspring appurtenant to said buffer, and againstwhich it yields.

2. In a loom, in combination, a rock-shaft having a lever-arm inconnection with the picker-stick and having a lever-like abutment orhorn, of a bracket secured on the end frame of the loom having upper andlower lugs provided with alined holes, a buffer-rod guided through saidalined holes, a spring against which the buffer may be yieldinglyforced, and means for limiting the movement of the buffer in thedirection of the spring stress thereagainst.

3. In a loom, in combination, a rock-shaft having a lever-arm inconnection with the picker-stick and having a lever-like abutment 0rhorn, of a bracket secured on the end frame of the loom having upper andlower lugs or members provided with alined holes, a buffer rod guidedthrough said alined holes, a spiral spring encircling the bufier-rodagainst which the buffer may be yieldingly forced, an adjustable collaron the buffer-rod for limiting the movement of the buffer in thedirection of the spring stress thereagainst, and another adjustablecollar on the bufier-rod against which one end of the spring is inbearing.

Signed by me at Springfield, Massachusetts, in presence of twosubscribing witnesses.
